This song is about the Battle of Gallipoli during World War I. It was fought between the ANZAC forces allied with the Triple Entente and the Ottoman Empire's forces allied with the Central Powers. There were almost 750,000 casulties for he whole battle on both sides and they were about evenly disributed between the two forces. This song is mainly about the ANZAC forces attempt to land in Sulva Bay, and due to the Ottoman Empire's entrenchments, they were slaughtered.

You posted within one minute after I linked the video, which means you didn't spend more than about 30 seconds listening to it. The English lyrics are on the original page.

Nonetheless, I think a sad melody is drastically different to a dramatic melody, and both of you linked two dramatic, but not very sad ones. I could never get emotional by listening to those two at all.
